I used it after heater blower fan would not work, stereo also dead, windshield wipers pooped. All Gouda now. Easy fix. Prices are going up. Put one away in your travel package. The metal clip must b for prevention of loosening out by vibration. But if the housing base is good, the old is difficult to remove. Sometimes must have to pry it out. Another reason to disconnect your ground at the battery before. Right? Right!
